title: Congestive heart failure: an unusual presentation of pseudohypoparathyroidism.
abstract: We report on an infant presenting with acute cardiogenic shock. She was eventually diagnosed with pseudohypoparathyroidism, which is a heterogeneous group of disorders characterized by severe hypocalcemia, hyperphosphatemia, and increased parathyroid hormone. The patient responded dramatically to calcium and vitamin D supplementation; left ventricular systolic function was normalized within days of treatment. Although the diagnosis of pseudohypoparathyroidism is rare, this case is a reminder of the importance of obtaining calcium levels in patients presenting in acute cardiogenic shock.
